I am looking to make a web comic, and was wondering what hardware do I need (besides a computer) to make it all possible? Do people scan their comics that they have drawn, and then post it? Or use a graphics program like Photoshop? Any help would be greatly appreciated. Thanks!

Hello Jeena1 and welcome to Tatsumaki, I dont know about Shiro and Suchi who are doing the more comedy based Webcomic but im doing the Manga Web Comic here on Tatsumaki. I draw my picture by hand pencils first, then i ink or paint them in photoshop. You could also use illustrator. And yes I scan my drawn pictures into the computer, you could also hand Ink your pics with a pen or brush and ink. So its really just a matter of what you prefer and whats available. I know I have been looking for people to help work on the Manga if youd be interested in that we could talk. I hope that all helps a little. And again welcome to Tatsumaki

Welcome, jeena1. (Edit: Spam links have been removed. Time to find out if this was a real post! Ready? Set? Go!)

Everything Yagyu said.

In addition, many people (Penny Arcade comes to mind, for example) use graphical software such as Photoshop (or it's free counterpart, GIMP 2) in combination with a tablet, such as the kind WACOM makes (this is what I use).

There are various other retail, free, and open source imaging programs out there - Inkscape is another example. Spend some time with Google if the examples in this thread don't work for you, and you'll eventually stumble upon something you like.
